Outline
Meme circulating via social media claims that October 2016 will have 5 Mondays, 5 Saturdays, and 5 Sundays, an event that only occurs once every 823 years.
Brief Analysis
It is perfectly true that October 2016 has 5 Mondays, 5 Saturdays, and 5 Sundays. However, such a combination is not at all remarkable and occurs far more often than once every 823 years. The last occurrence was in October 2011 while the next occurrence will take place in October 2022. In reality, any month that has 31 days will have three consecutive days that occur five times in the month. Such combinations are commonplace and occur each and every year. This meme is just an updated version of several earlier – and equally nonsensical – chain messages.
